Following years of effort, the first stage of Cardano’s Chang upgrade has gone live, transitioning ownership of the blockchain to holders of its native ADA token. With the upgrade, Cardano enters its final stage of development, dubbed the Voltaire era. 
Cardano, the Layer 1 blockchain founded by Ethereum co-founder Charles Hoskinson, has officially undergone the first stage of its Chang hard fork, becoming the first major blockchain to transition its centralized governance structure to a token-based decentralized governance system. 
Over the next 90 days, Cardano will undergo a full transformation to a community-led governance model overseen by an interim committee. At the end of the 90 days, the second stage of the Chang hard fork will activate, fully turning power over to its new governance bodies, which include a constitutional committee, delegate representatives, and staking pool operators. 
"The goal of the first stage is to ensure security and continuity during the governance bootstrapping phase, allowing [delegate representatives] to register and campaign for delegation, while developing and ratifying a final constitution by early 2025," Cardano's explanation reads. 
While at times Cardano ranked in the top 5 cryptocurrencies by market cap, recent dynamics have been less than favorable for the token, which fell out of the top 10 last month as TRON's TRX token and Telegram's Toncoin have grown. 
"When I reflect back at where we started as an ecosystem it was just an idea...we've grown tremendously throughout the years. There've been ups and downs, there's been a lot of disappointments, but now we are here," Hoskinson said in a video posted to X. "Now we are here today...a day where the entire ecosystem, the community, every holder of ADA stands shoulder to shoulder as equals and they all have a say in the future not just of this protocol, but what this protocol can do for everyone in the world."

Polygon has regained control of its community Discord server following a hack that allegedly cost one user about $145,000 in assets. The attack, seemingly from a serial hacker, comes shortly before Polygon’s planned mainnet upgrade on Sep. 4, which will transition its native token MATIC to a new token with the ticker POL. 
Polygon has regained control of its community Discord after it was hijacked for about four hours on Saturday morning, allegedly leading to the theft of about $145,000 in assets from one user. 
"We have regained access and secured the Polygon community discord server. All external bots and integrations have been disabled while we perform a security review of each of them to avoid this from happening again," Polygon wrote on X. 
A fraudulent message was posted to the Polygon Discord at about 5 am GMT, seemingly from the account of its community lead Smokey, contemporaneous screenshots show. The message advertised a "special pre-migration" airdrop ahead of the Polygon network's planned migration from its native MATIC token to the upgraded POL token, which is scheduled for Sep. 4, along with a phishing link. 
At least one user claims to have fallen victim to the attack, and blockchain data backs up their claim of losing a Uniswap position worth about $145,000 in the hack. The transfer transaction occurred about 40 minutes after Polygon's chief information security officer, Mudit Gupta, alerted the Polygon community to the hack with a post on X, which was reposted by Polygon's X account, though it's unclear when the repost occurred. 
The wallet address where the Uniswap position was transferred, which likely belongs to the hacker, appears to have claimed other victims in the past. Ten days ago, the wallet transferred ether worth $72,300 at the time to a wallet flagged by Etherscan as a phishing perpetrator that now holds nearly $400,000 in assets. Five days ago, the wallet transferred $29,500 worth of ether to a different, but similarly flagged, wallet with $150,000 in assets.
Polygon's team is currently unsure of the mechanism by which its Discord was compromised. "At this moment, we don't believe any of our mods were compromised this way [being phished]. It seems more likely that a bot/integration we had was compromised. Still going through the logs," Gupta posted on X. Gupta also stated that the team plans on releasing a postmortem following a review of the hack.
